Description

一种控弯型PTCA导丝
技术领域
本发明涉及一种PTCA导丝，具体是一种控弯型PTCA导丝。
背景技术
采用股动脉或者桡动脉穿刺通过PTCA导丝将球囊导管送至冠状动脉狭窄病变处，加压扩张，并且释放支架以增大血管内径，改善心肌血供，英文简称PTCA。PTCA手术中常常遇到导丝在多分枝血管中因为之前的导丝塑性不合适或者血管成角大，导致难以操控导丝进入到目标血管，给手术带来一定的困扰，甚至需要将导丝撤回重新塑性，若是多次遇到多分支血管，往往会造成因为导丝塑性角度不合适的问题导致手术失败。
发明内容
本发明的目的在于提供一种控弯型PTCA导丝，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种控弯型PTCA导丝，包括绕丝、支撑管、右控弯线、左控弯线和控弯手柄，所述右控弯线和左控弯线均滑动设置在支撑管内部，左控弯线和右控弯线之间设有间隙，右控弯线和左控弯线的一端穿出支撑管并连接呈半圆球状的头端，右控弯线和左控弯线的外部套设有绕丝，绕丝设置在头端和支撑管的端面之间；支撑管的一端置于控弯手柄内，控弯手柄的左右两侧分别设有左控弯控制器和右控弯控制器，左控弯控制器和右控弯控制器分别连接左控弯线和右控弯线。
作为本发明进一步的方案：所述支撑管和绕丝的外部均设有亲水涂层。
与现有技术相比，本发明的有益效果是：左控弯控制器和右控弯控制器分别控制左控弯线和右控弯线的张紧和放松，左控弯线张紧时，头端向左偏摆，右控弯线张紧时，头端向右偏摆，偏摆角度根据绷紧的程度决定，在造影剂和X射线帮助下轻松的将导丝头端调成需要的角度，从而进入到所需血管内，并且没有遇到迂曲血管时候可以将导丝变为直型导丝，这样减少导丝对血管壁的损伤，绕丝的设置可以使得头端在接触人体组织和血管时存在一个缓冲的过程，减少绕丝对血管壁的损伤，同时还可以增加头端的灵敏度，增强医生的触感。
附图说明
图1为一种控弯型PTCA导丝的结构示意图。
图中：1-绕丝、2-支撑管、3-右控弯线、4-左控弯线、5-控弯手柄、6-左控弯控制器、7-右控弯控制器、8-头端。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明实施例中，一种控弯型PTCA导丝，包括绕丝1、支撑管2、右控弯线3、左控弯线4和控弯手柄5，所述右控弯线3和左控弯线4均滑动设置在支撑管2内部，左控弯线4和右控弯线3之间设有间隙，右控弯线3和左控弯线4的一端穿出支撑管2并连接呈半圆球状的头端8，右控弯线3和左控弯线4的外部套设有绕丝1，绕丝1设置在头端8和支撑管2的端面之间，绕丝1的设置可以使得头端8在接触人体组织和血管时存在一个缓冲的过程，减少绕丝对血管壁的损伤，同时还可以增加头端8的灵敏度，增强医生的触感；支撑管2的一端置于控弯手柄5内，控弯手柄5的左右两侧分别设有左控弯控制器6和右控弯控制器7，左控弯控制器6和右控弯控制器7分别连接左控弯线4和右控弯线3，可以控制左控弯线4和右控弯线3的张紧和放松，左控弯线4张紧时，头端8向左偏摆，右控弯线3张紧时，头端8向右偏摆，偏摆角度根据绷紧的程度决定，可以使得导丝在遇到不同的成角血管时候都能根据实际情况做不同程度的控弯，轻松自如的进入到需要血管腔内。
所述支撑管2和绕丝1的外部均设有亲水涂层，保证导丝运动时的顺滑性。
本发明的工作原理是：左控弯控制器6和右控弯控制器7分别控制左控弯线4和右控弯线3的张紧和放松，左控弯线4张紧时，头端8向左偏摆，右控弯线3张紧时，头端8向右偏摆，偏摆角度根据绷紧的程度决定，在造影剂和X射线帮助下轻松的将导丝头端8调成需要的角度，从而进入到所需血管内，并且没有遇到迂曲血管时候可以将导丝变为直型导丝，这样减少导丝对血管壁的损伤，绕丝1的设置可以使得头端8在接触人体组织和血管时存在一个缓冲的过程，减少绕丝对血管壁的损伤，同时还可以增加头端8的灵敏度，增强医生的触感。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
